Hello All, first time post and thanks in advance

I picked up this old Audition 12 transistor radio but don’t seem to find much about it on the web. I don’t see a specific model listed anywhere but a serial number. I thought this would be cool for my daughter and I to work on. It still has the battery tube for four D sized batteries (6v) but haven’t tried it yet. The on off knob to the left seems stuck and will have to figure out how to get that off before I can slide the board out of the back.

Anyone recognize this thing at all?

Manufactured in Japan for F. W. Woolworth stores. There may be a small schematic pasted to the inside of the cabinet. At times it is underneath the top.

Standard operating procedure is to replace all the electrolytic capacitors, one at a time, so you don't get lost. Mark their negative side on the circuit-board with a sharpie prior to removal.

Modern day electrolytic capacitors have become...

Do not touch the dial-string with your soldering iron - it won't like it. Lol


Yay for girls... they excel at math and science all through High school, yet engineering is still a very much male-dominated world!

Welcome to the hood... :)

oh... difficult knobs.

The dial has Civil Defense Marks, the dots after 60 and under 12 (640 and 1240 Kc), indicating manufacture before about 1963. Another indication of "antiquity" is that the AM band is above the FM band on the dial.

Use a piece of fabric, like a T-Shirt, to loop behind the knob, and pull it off. You could shoot some WD-40 on the shaft and turn it face down for a few seconds, to maybe lubricate between the knob and the shaft.
